|
|
// logs may end up interrupted by logs on other threads. This is usually not a problem for
|
|
// WriteLn, but may be undesirable for typical uses of Write. In cases where you want to
|
|
// print multi-line blocks of uninterrupted logs, compound the entire log into a single large
|
|
// string and issue that to WriteLn.
